Planting Citrus should promote the differentiation of Citrus Flower Bud in time

Since the beginning of winter, the temperature continues to be warm, the soil water content of citrus orchard is more, and some citrus trees begin to sprout winter shoots, which is very disadvantageous to citrus flower bud differentiation this winter. If not handled properly, it will have a serious impact on citrus production next year. Citrus growers should do a good job in the implementation of citrus flower promotion measures in time. For citrus trees that germinate winter shoots, all those whose winter shoots do not turn green should be picked in time, and they should be sprayed with paclobutrazol and dormancy to promote flowers; when winter shoots basically turn green, foliar fertilizers such as potassium dihydrogen phosphate should be sprayed to promote shoot ripening.

The temperature in Sihui City continues to be warm this year, and it is more suitable to adopt the measures of ring cutting to promote flowers for citrus trees and fruiting trees with relatively strong growth. The specific method is to cut the trunk or branches of citrus trees with a knife in order to achieve a better effect of promoting flowers. In addition, the ring cutting to avoid windy weather, if encountered within 10 days after the ring cutting cold north wind should be timely sprinkling water to protect leaves.

After ring-cutting or root-cutting treatment, citrus trees with thick green leaves should be sprayed twice before the end of December with flower promoters such as Flower Guoling and Huaduoduo.

Now it is the citrus fruit harvest season. After fruit harvest, the citrus trees with hanging fruit should be sprayed with 1Mel twice nucleotide foliar fertilizer to increase the concentration of citrus sap and promote flower bud differentiation. For citrus trees with too many fruits and lighter leaves, it is necessary to apply fertilizer before and after fruit harvest, mainly phosphorus and potassium fertilizer, so that the fruit trees can quickly restore their potential.

While grasping the implementation of flower promotion measures, we should make use of the favorable opportunity of easy identification of citrus Huanglong disease in winter to do a good job in the prevention and control of citrus diseases and insect pests in time, thoroughly dig out the diseased plants of Huanglong disease and burn them outside the orchard to ensure the normal growth of citrus.
